A slider comprising a body having an air bearing surface (ABS), wherein the ABS extends between a leading edge and a trailing edge of the body. The slider comprises a transducer supported by the body and positioned near the trailing edge, wherein the transducer comprises a pole tip partially extending from the body. The slider comprises a surface defined in the body and forming the trailing edge, wherein the surface comprises a plurality of segments. A first segment of the plurality of segments extends from the ABS and is offset from a portion of the pole tip recessed within the body. The first segment is offset from the pole tip portion by a lesser extent than any other of the plurality of segments.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method of shaping a trailing edge of a slider, the method comprising: encasing a transducer in alumina, the transducer on a wafer of ceramic material and including a pole tip; forming a trench above an end of the pole tip; and making a series of cuts into the alumina relative to a pole tip of the transducer to differentiate a slider head, wherein each cut of the series of cuts extends to one side of a respective pole tip, around the respective pole tip, and continues on another side of the respective pole tip.
2. The method of claim 1 wherein the ceramic material comprises AlTiC.
3. The method of claim 1 wherein the transducer is a part of a plurality of transducers provided in one or more rows on the wafer.
4. The method of claim 3 wherein the trench is one of a plurality of trenches each of which is consistently formed with respect to one of the transducer pole tips.
5. The method of claim 4 wherein each of the trenches is formed using an etching process.
6. The method of claim 5 , wherein each of the trenches includes a first segment that extends substantially parallel to the corresponding pole tip and wherein each trench includes a second segment that extends from the first segment in a direction perpendicular to a trailing edge surface of the slider at an angle of greater than 90 degrees.
7. The method of claim 1 , wherein the pole tip protrudes from the alumina.
